Definitions

  • the invention relates to pellets which contain at least one oily component, which in itself represents an active component or contains at least one such active component.
  • oily and / or active components are often sensitive to oxidation or volatile, so that the proportion of such active components is reduced or these components lose their effect over more or less long periods of time.
  • pellets according to the invention can be selected by appropriate selection of suitable active ver components are used as food for animals and humans as pharmaceutical forms, for detergent additives, as pesticides and others.
  • the emulsions are processed into powders. As described in EP 0 598 920 B1, this is done by spray drying an emulsion. According to the teaching that can be found there, an emulsion with an oil phase and a very specific soybean He-i cellulose, which is water-soluble, is produced as an emulsifier. A spray in the form of microcapsules is produced from this emulsion by spray drying. In addition to the oily phase, the microcapsules can also contain other or further active components.
  • the conventional powders made from emulsions have a limited mechanical strength, so that a high level of abrasion occurs in particular during transport and storage, or it even breaks
  • the powders produced by spray drying are only partially flowable, so that precise dosing can only be achieved with great effort.
  • powder particles are to be coated with an outer protective coating to improve the above-mentioned properties, a very large amount of coating material is required because of their very large surfaces.
  • Mass ratios of powder and coating material of up to 1: 1 may be required for the formation of dense coatings, which leads to increased manufacturing costs and a reduction in the proportion of active component to the volume of the mass leads .
  • pellets which have the features of claim 1.
  • the pellets according to the invention can be produced using a method according to claim 24.
  • Advantageous further developments and refinements of the invention can be achieved with the features contained in the subordinate claims.

  • a matrix which contains a water-soluble polysaccharide as film former.
  • the high proportion of active components contained in such pellets can be achieved, in particular, by the production method which is also according to the invention. gen, can be achieved.
  • the film-forming polysaccharide to be used according to the invention should contain at least 0.5% by mass.
  • the proportion of these film formers can, however, also be selected to be significantly larger and amount to up to 60% by mass.
  • the film former used ensures that the one or more components included in the matrix can be enclosed in the matrix in the form of discretely arranged capsules.
  • Particularly suitable polysaccharides for this purpose have been water-soluble hemi-cellulose, which can be obtained, for example, from soybeans or rapeseed and / or modified starch and / or pectin compounds.
  • the water-soluble polysaccharides are physiological and harmless to the environment.
  • Gum arabic is available in almost the same quality and at almost constant costs, i.e. regardless of weather conditions that affect the prices of natural film-forming substances.
  • Carbohydrates that are not soluble in water can be used for the matrix. These can be selected from starches or cellulose components. Different starches can be used to form the matrix, malt starch but also cereal starch being particularly suitable for this. These can be used alone or in combination with each other.
  • Microcrystalline cellulose is particularly suitable as a cellulose component for the matrix formation.
  • the mass fraction of starch can be kept up to a maximum of 90 mass%.
  • pellets according to the invention with water-soluble carbohydrates. Pellets can thus be produced in a continuous spray granulation process in which such carbohydrates are contained in the matrix and water-soluble polysaccharides act as film formers.
  • pellets can be influenced within wide limits with water-soluble carbohydrates.
  • a particle size of such pellets in the range between 200 ⁇ m to 1500 ⁇ m can thus be obtained.
  • An active component with more than 15% by mass can be encapsulated.
  • Suitable carbohydrates for this are different oligosaccharides with different chain lengths.
  • Dextrins are particularly suitable for this purpose and maltose dextrins are very particularly suitable.
  • a matrix can also be formed from inorganic components or contain such components.
  • Suitable inorganic substances are, for example, kaolin, CaC0 3 , CaS, silicates, clay, bentonite, diatomaceous earth or aluminum oxide, which can also be used as a mixture.
  • the inorganic components should also be largely insoluble in water.
  • monosaccharides, disaccharides or trisaccharides can also be present, with different proportions by mass, which can be above 50% by mass, also being maintained here.
  • oily components with active action can also be used for the production of pellets according to the invention.
  • the proportion of this component should preferably be at least 15% by mass.
  • the various fruit oils but also fruit oil extracts have proven to be particularly advantageous for this.
  • the oily component can be formed from orange and / or lemon oil. Even the aromatic taste and smell of these oily components can achieve the desired active effect alone, if appropriate, but also with additional active components.
  • synthetic or natural dyes can also be used as an additional active component.
  • carotene preferably beta carotene, kantaxanthin or astaxanthin, which in addition to the effect of the dye have the known additional effects, can be used for this purpose.
  • vitamins preferably vitamins soluble in oil, such as, for example, vitamin A acetate, can also be used as active components, and a combination of these vitamins with carotene is also possible.
  • active components In addition to the vitamins, other pharmaceutically active substances can also be used as active components.
  • Other possible active components are various insecticides / biocides.
  • Flavorings with a taste and / or fragrance can be used for food.
  • unsaturated fatty acids such as e.g. Alpha-omega polyunsaturated fatty acids are used.
  • active components contained in the capsules in addition to the oily component do not necessarily have to be oil-soluble. They can also be contained in dispersed form as small crystals in an oily component. So there is the possibility of unstable vitamins, e.g. to disperse the vitamin K (MSBC) finely crystalline in an oily component and to encapsulate it in the pellets with the oily component.
  • MSBC vitamin K
  • the proportion of the volume occupied by the capsules embedded in the matrix should be above 10%, preferably kept above 20%. However, it is also possible to set the corresponding volume proportion beyond this and accordingly to significantly increase the proportion, ie the loading with active components in the pellets.
  • the water content in the finished pellets should be kept below 10% by mass.
  • the pellets according to the invention are obtained by a combination of emulsion production with subsequent direct pelleting or extrusion.
  • At least one starch, an oily component, a water-soluble polysaccharide as film former and water are used for the preparation of the emulsion.
  • starch can additionally be added to the emulsion obtained therefrom in order to increase the viscosity and establish a pasty consistency.
  • an extrusion can preferably take place, in which case the still slightly moist pellets can then be removed from the respective extruder. If necessary, the pellets can also be mechanically reworked, preferably rounded.
  • Additional drying can follow in order to further reduce the water content and there is also the possibility of providing the individual pellets with a protective coating, which preferably forms and protects against moisture. can also prevent the pellets from sticking together.
  • an emulsion in which an oily component is at least finely dispersed and with a water-soluble polysaccharide as film-former by e.g. Adding viscosity-increasing starch during an extrusion, the capsules formed which contain the oily component and optionally further active components are embedded in the matrix and are not destroyed in the process.
  • a homogeneous that is, a very uniform distribution of the small capsules within the matrix of the individual pellets can be achieved.
  • a more or less large loading that is to say a corresponding proportion of active components, can be set, which can be maintained up to 20% by mass and also beyond.
  • Relatively fine nozzles can also be used in the extrusion, so that the pellets can have diameters in the range of around 1 mm orthogonal to the extrusion direction after the extrusion.
  • Extrusion can be carried out at a temperature which is in particular lower than that of spray drying, so that the active components used are also less negatively influenced thereby. There are fewer evaporation losses. Relatively low pressures can be used for extrusion. This also enables gentle treatment of the encapsulated active components and ensures that the active components can be protected from the undesired external influences and can be kept securely enclosed within the matrix of the pellets.
  • the starch and / or cellulose component used essentially for the formation of the matrix is physiological and harmless to the environment and predominantly also odorless and tasteless.
  • pellets produced according to the invention also have good mechanical stability, so that reduced abrasion can be achieved.
  • pellets thus obtained were then rounded det and subsequently dried in a fluidized bed until a water content of about 4% could be maintained.
  • the dough-like consistency was adjusted by adding 9 kg of cereal starch, followed by rounding and subsequent drying to a water content of approx. 4% by mass.
  • the non-anionic acid was safely encapsulated in the pellets and no shrinkage was found.
  • 125 g of powdered malt starch were mixed with 125 g of soybean-based powdered hemi-cellulose.
